Top-speed processor cuts power as well

Operating at clock speeds up to 1GHz, the PowerPC 750FX is ideal for systems such as storage, imaging, networking, consumer-based desktop and portable computing and other consumer applications.

Operating at clock speeds up to 1GHz, the PowerPC 750FX is ideally suited to a variety of systems, including storage, imaging, networking, consumer-based desktop and portable computing and other consumer applications.

Typical systems will turn in benchmarks of around 2300 Dhrystone MIPS at 1GHz.

At the same time, power dissipation is minimised through advanced process technologies.

The 750FX consumes only 3.6W (typical) at 800MHz, making it much more power-efficient than other microprocessors with comparable performance.

To support high performance applications, the new chip from Sequoia increases bus bandwidth by improving both frequency and bus usage.

This IBM chip supports bus frequencies of up to 200MHz, and - in addition to frequency improvements - has extra pipelining to provide up to 25% better performance than previous PowerPC devices.

The superscalar architecture includes 512K of internal on-chip L2 cache running at processor frequency, and uses an efficient five-stage pipeline to minimise latency.

Sequoia's new processor is the first PowerPC to combine all IBM's most advanced process technologies onto one chip, reducing power consumption by up to 50% or increasing performance by up to 30%.

Manufactured in an advanced 0.13-micron technology, the chip is the first to include copper interconnects, silicon-on-insulator (SOI) transistors and low-k dielectric insulation technologies.

The PowerPC 750FX is available from Sequoia in 256-pin PBGA packages and supported by in-depth technical and design-in expertise from the company's components group.
